Wastebasket or bin having rocking springs at bottom

ABSTRACT

The paper shredder of this invention includes a machine body having cutting blades therein and a wastebasket or bin for containing paper chips, including a base provided beneath a wastebasket or bin; at least one support spring provided between the base and the wastebasket or bin to form an appropriate gap between the wastebasket or bin and the base, whereby when the user rocks the wastebasket or bin forwards and backwards, or sideways, chips in a chip mountain accumulated beneath the discharge port at the cutting blades can be spread outwards, to increase the space for receiving the paper chips in the wastebasket or bin, to prevent the “chip mountain” from impeding smooth falling of subsequent paper chips, thereby affecting overall operative functions of the paper shredders.

FIELD OF INVENTION

This invention relates to an improved wastebasket or bin for a papershredder, particularly to one having an improved rocking wastebasket orbin for overcoming the problems caused by chip mountain formed by paperchips accumulated beneath the discharge port at the cutting blades ofthe paper shredder, which may impede smooth falling of subsequent paperchips, thereby affecting overall operative functions of the papershredder.

BACKGROUND

The conventional shredders for cutting paper use a plurality of cuttingblades and spacers engaging over a rotary shaft, and the shearing forcethat two parallel and opposite rotary shafts produced by a motor and agear box for transferring and cutting the paper-to-be-cut along alongitudinal direction into strips. Shredders can be classed into twotypes, the stripe-cut shredders and crosscut shredders, according to themachine cutting style. The former shredders arrange cutting blades tothe rotating shafts in a manner to cutting the paper in a longitudinaldirection to form strips. The later shredders include blades thatinclude more than one cutting edge part, and each cutter is disposedhelically along the rotary shaft for first cutting paper along ahorizontal direction into strips and then cutting paper along alongitudinal direction into approximate 4 mm×40 mm paper chips.Regardless of being stripe-cut shredders and crosscut shredders, abasket or bin for containing paper chips usually accompanies theshredder at sales.

Regardless of stripe-cut shredders and crosscut shredders, a wastebasketor bin for containing paper chips is usually accompanied with the papershredder on sales. As stated, the cutting blades engaging over a rotaryshaft, and the shearing force that two parallel and opposite rotaryshafts produced by a motor and a gear box serve to transfer and cut thepaper-to-be-cut along a longitudinal direction into strips or chips,which are then dropped into the

wastebasket or bin through a discharge port located at a bottom of thepaper shredder. Along with the increasing amount of chips, the paperchips would gradually accumulate to from a chip mountain. When the chipmountain has reached a height that is close to the discharge port of thepaper shredder, it may impede smooth falling of subsequent paper chips,or even cause the paper chips to be drawn into the rotary shafts andjamming the gaps between the cutting blades, thereby affecting overalloperative functions of the paper shredders.

Experiences show that, upon forming a “chip mountain,” the user onlyneeds to spreading the mountain-like chips outwards to increase thespace for receiving the paper chips in the wastebasket or bin, toprevent the “chip mountain” from impeding smooth falling of subsequentpaper chips, or causing the paper chips to be drawn into the rotaryshafts and jamming the gaps between the cutting blades, therebyaffecting overall operative functions of the paper shredders.

SUMMARY OF INVENTION

It is a primary object of this invention to provide the user with a wayfor spreading the “paper mountain” accumulated beneath the dischargeport of the paper shredder outwards by simply rocking the wastebasket orbin so as to overcome the problems caused by paper chips that areimpeded from smooth falling, or drawn into the rotary shafts and jam thegaps between the cutting blades, thereby affecting overall operativefunctions of the paper shredders.

It is another object of this invention to provide the user with a wayfor spreading the “paper mountain” accumulated beneath the dischargeport of the paper shredder outwards by simply rocking the wastebasket orbin so as to increase the space for receiving the paper chips in thewastebasket or bin.

To achieve the above objects, this invention provides a base beneath thewastebasket or bin, where at least one support spring is providedbetween the base and the wastebasket or bin, to form an appropriate gapbetween the wastebasket or bin and the base, such that when the userrocks the wastebasket or bin forwards and backwards, or sideways, thechips in the chip mountain accumulated beneath the discharge port at thecutting blades can be spread outwards, so as to increase the space forreceiving the paper chips in the wastebasket or bin, and to prevent the“chip mountain” from impeding smooth falling of subsequent paper chips,thereby eliminating the defects of affecting overall operative functionsof the paper shredders.

DETAILED DESCRIPTION OF THE INVENTION (PREFERRED EMBODIMENTS)

With reference to FIGS. 1 to 4, the paper shredder 1 of this inventionincludes a machine body 12 having cutting blades 11 therein and awastebasket or bin 13 for containing paper chips. The cutting bladesengage over a rotary shaft, and the shearing force that two parallel andopposite rotary shafts produce by a motor and a gear box serve totransfer and cut the paper-to-be-cut along a longitudinal direction intostrips, or further shredded in chips. The machine body 12 is provided atits surface with a paper inlet 121 parallel to the cutting blades, so asto guide the paper into the rotary shafts of the cutting blades 11 forshredding the paper.

The wastebasket or bin 13 is provided therebeneath with a base 14. Atleast one support spring 13 is provided between the base 14 and thewastebasket or bin 13. The support spring 13 is mounted between anupward-projecting post 141 of the base 141, and an indent 131 at thebottom of the wastebasket or bin 13 indenting inwards, so as to form anappropriate gap between the wastebasket or bin 13 and the base 14, toserve as a space where the rocking wastebasket or bin 13 may move about.

When the user rocks the wastebasket or bin forwards and backwards, orsideways, the chips in the chip mountain accumulated beneath thedischarge port at the cutting blades 11 can be spread outwards, so as toincrease the space for receiving the paper chips in the wastebasket orbin, and to prevent the “chip mountain” from impeding smooth falling ofsubsequent paper chips, thereby eliminating the defects of affectingoverall operative functions of the paper shredders.

Since the paper shredder 1 and the wastebasket or bin 13 are supportedby springs 15, rocking of the springs will directly affect steadiness ofthe wastebasket or bin 13. Accordingly, appropriate number for andlocations of arranging the springs can be adjusted in accordance withthe different spring characteristics. For example, in FIG. 1, foursprings 15 are arranged at four corners of the wastebasket or bin 13; inFIG. 3, three springs 15 are arranged at bottom of the wastebasket orbin 13 in a triangular configuration; or in FIG. 4, a single spring 15is arranged at a bottom center of the wastebasket or bin 13, where allarrangements can achieve the object of featuring the wastebasket or binwith rocking capability.

Accordingly, the user can rock the wastebasket or bin 13 at appropriatetiming to rock the wastebasket or bin forwards and backwards, orsideways, for spreading the chips accumulated beneath the discharge portat the cutting blades outwards, so as to increase the space forreceiving the paper chips in the wastebasket or bin, and to prevent the“chip mountain” from impeding smooth falling of subsequent paper chips,thereby eliminating the defects of affecting overall operative functionsof the paper shredder.

In summary, this invention provides an improved paper shredderwastebasket that may not only serve as a wastebasket for containingpaper shreds after the paper shredder shreds paper, but also be liftedoutwards to serve as a conventional garbage bin, so as to improve themarket competitiveness of the paper shredder by enhancing the functionsof the wastebasket.
